Abstract

h-BN/Si₃N₄ composite ceramics were fabricated by gel-casting method and pressureless sintering using Si₃N₄ and h-BN as raw materials. The effect of h-BN on the microstructure and comprehensive properties of h-BN/Si₃N₄ ceramic were investigated. The results showed that the introduction of h-BN hindered the densification of h-BN/Si₃N₄ ceramic as well as the transformation of α-Si₃N₄ to β-Si₃N₄. The mechanical properties of Si₃N₄ based ceramics decreased with the increase of h-BN content, while the thermal property, dielectric properties and machinability increased.
